Momwe mungasankhire mandala aukadaulo

Monga gawo lofunikira la m'maganizo mwa makina, makamera ogulitsa mafakitale nthawi zambiri amakhazikitsidwa pamsonkhano wa pamsonkhano kuti usinthe diso loti muthe kuyeza ndi kuweruza. Chifukwa chake, kusankha mandala abwino kuli kamera ndi gawo lofunikira kwambiri pamakina opanga makina.

Chifukwa chake, tiyenera kusankha bwanji zoyeneraMasewera a Makamera a Fakitala? Ndi nkhani ziti zomwe ziyenera kulingaliridwa posankha mandala a makamera? Tiyeni tiwone limodzi.

1.Malingaliro oyambira posankha ma tayi a kamera

①Sankhani kamera ya CCD kapena CMOS malinga ndi mapulogalamu osiyanasiyana

CCD mafayilo a kamera amagwiritsidwa ntchito makamaka pochotsa zithunzi zosuntha. Zachidziwikire, ndikukula kwaukadaulo wa CMOS, makamera a makonda a CMOS amagwiritsidwanso ntchito makina ambiri oyenda. Makamera a CCD ogulitsa mafakitale amagwiritsidwa ntchito kwambiri m'munda wamayendedwe owoneka bwino. Makamera a CMOS amagwiritsidwa ntchito kwambiri chifukwa cha mtengo wawo wotsika komanso kugwiritsa ntchito mphamvu zochepa mphamvu.

Makamera okhala ndi mafakitale amagwiritsidwa ntchito popanga mizere yopanga

②Kusintha kwa ma tayi a kamera

Choyamba, lingaliro limasankhidwa polingalira za kulondola kwa chinthucho chikuwonedwa kapena kuyezedwa. Ngati kamera pixel = gawo limodzi lotsogolera kukula / mtundu wa kamera kamodzi, kenako njira yoyeserera yokha-pompoom-templen.

Ngati gawo limodzi la malingaliro ndi 5mm ndi zolondola za chiphunzitso ndi 0.02mm, chiwonetsero chimodzi ndi 5 / 0.02 = 250. Komabe, kuti awonjezere kukhazikika kwa dongosololi, sizotheka kufanana ndi muyeso / kuwunikira molondola ndi pixel imodzi yokha. Nthawi zambiri, zoposa 4 zitha kusankhidwa, kotero kamera imafunikira ma pixel amodzi a 1000 ndi 1.3.

Kachiwiri, poganizira za kutulutsa kamera kwa mafakitale, kusintha kwapamwamba kumathandiza pakuwunikira kapena kusanthula kwamakina. Ngati ndi VGA kapena USB zotulutsa, ziyenera kuonedwa pa polojekiti, motero kuwunika kuyenera kuganiziridwanso. Ziribe kanthu kuti kusintha kwa ukadaulo wa mafakitale kumachitika ndiMagawo a kamera a mafakitale, sizingamveke bwino ngati kusintha kwa wowunikira sikokwanira. Kusintha kwa makamera ogulitsa kumathandizanso ngati kugwiritsa ntchito makhadi okumbukira kapena kujambula zithunzi.

③Kamera ya kameramtengoya makoswe a kamera

Pamene chinthucho chikuyesedwa ndikuyenda, mandala a kamera opanga mafakitale okhala ndi mtengo wapamwamba ayenera kusankhidwa. Koma nthawi zambiri, olankhula kwambiri, otsika mtengo.

④Kufananira ndi magalasi a mafakitale

Kukula kwa Syrr Chip kuyenera kukhala kocheperako kapena wofanana ndi ma lens kukula, ndipo ma C kapena C kapena CS HUPT Ayeneranso kufanana.

①C-Mount kapena CS-Phiri

Kutalikirana kwa ma C-Phiri ndi 17.5mm, ndipo mtunda wautali wa CS-Ps-Ps-Pster ndi 12.5mm. Mutha kungoyang'ana mukasankha mawonekedwe olondola.

Kusiyana pakati pa mawonekedwe osiyanasiyana

②Kukula kwa chipangizo chaphika

Kwa 2/3-inchi yachip yavithttive, muyenera kusankhaMasewera a Makamera a Fakitalazomwe zikufanana ndi zongoyerekeza. Ngati mungasankhe 1/3 kapena 1/2 inchi, ngodya yayikulu yakuda idzawoneka.

③Sankhani kutalika kwambiri

Ndiye kuti, sankhani mandala ogulitsa mafakitale ndi gawo la kuwona bwino pang'ono kuposa mtundu wowonera.

④Kuya kwa munda ndi malo owala kuyenera kufanana

M'malo okhala ndi kuwala kokwanira kapena kuwala kwakukulu kwakukulu, mutha kusankha pang'ono kuti muwonjezere mawonekedwe a mundawo ndikuwongolera momveka bwino; M'malo okhala ndi kuwala kosakwanira, mutha kusankha chopinga chachikulu pang'ono, kapena sankhani chithunzi chokulirapo ndi chidwi chachikulu.

Kuphatikiza apo, kuti musankhe mandala aukadaulo, muyenera kutchera chidwi ndi zochitika zosiyanasiyana. Mwachitsanzo, mafayilo ojambula apita patsogolo kwambiri m'zaka zaposachedwa, ndikupita ku ma pixel ochulukirapo kuti asintheMagawo a kamera a mafakitale, komanso chidwi chapamwamba (zowonjezera zojambula). Kuphatikiza apo, ukadaulo wa CCD wakhala wothandiza kwambiri ndipo tsopano amagawana kwambiri ndi masensa a CMOS.

Maganizo omaliza:

Chuangin yachita kapangidwe kake ndi kupanga kwa magalasi a kamera a mafakitale, omwe amagwiritsidwa ntchito pazinthu zonse za ntchito zama mafakitale. Ngati mukufuna kapena mukufunika ma tayi a kamera a mafakitale, chonde titumizireni posachedwa.
